Definitions

  • the present invention relates to a machine for swathing, turning swaths or tedding cut plants on the ground.
  • machines are generally used provided with flexible fingers which have in particular the drawbacks of acting brutally on dry plants and of mixing foreign bodies such as stones, broken fingers or the like with fodder.
  • Machines moving plants by pneumatic device eliminate these drawbacks.
  • Such machines are known in patent application DE-B-1 110 458 or WO-A-85 000 88 or FR-A-2 437 771.
  • the air produced by a fan is directed towards the ground in a direction slightly inclined relative to the surface of said soil.
  • cut plants are placed on the ground and are practically pushed into the uncut feet of these plants. Consequently, the movement and separation of these plants is generally very difficult, especially when they are dense and heavy.
  • the object of the present invention is a machine with a device for moving plants on the ground by means of the air produced by at least one fan in at least one sheath or similar duct, not having the drawbacks of known machines.
  • an important characteristic of the invention consists in that the blown air arrives substantially vertically on the plants and that the machine comprises a deflector for orienting the plants which at least partially surrounds the duct (s) air inlet.
  • the power of the air from the fan or fans arrives more or less vertically on the plants.
  • the air then passes between the soil and said plants, lifts them up, separates them and moves them according to the desired work.
  • the orientation deflector channels the air flow towards the place where the plants are to be placed on the ground.
  • the machine comprises several fans mounted in gains arranged in an oblique line with respect to the direction of advance.
  • the plants are thus moved laterally from one air intake duct to the other, so as to obtain a large working width.
  • the machine according to the invention can also include several fans mounted in gains arranged on two lines forming a V whose tip is directed towards the rear. In this case, the plants are moved from one air intake duct to the other, up to the point of the V and, are deposited on a central swath.
  • the displacement of the plants along the oblique line or the V-shaped lines, along which the air inlet gains are arranged, is improved by means of lateral openings provided in these sheaths. These openings are directed in the direction of movement. The air exiting through these openings reinforces the air flow which transports the plants so that there is no accumulation of plants in front of or between the sheaths, especially when they are dense and / or heavy.
  • the machine according to the invention comprises a frame (1) produced by means of beams.
  • This frame (1) is provided with a three-point hitching device (2) for coupling to the lifting device of a not shown drive tractor.
  • said frame On the side opposite to that on which the coupling device (2) is located, said frame comprises two rollers (3 and 4) which move on the ground during work.
  • These rollers (3 and 4) are fixed on columns (5 and 6) which are pivotally housed in bearings (7 and 8) integral with the frame (1). Said rollers can be moved along the columns (5 and 6) and be stopped in different positions by means of locking screws.
  • the frame (1) also comprises a crosspiece (9) carrying the displacement device (10). In the example shown, it consists of three fans (11). This number can vary depending on the desired working width. Said frame (1) also carries a deflec tor (12) which guides the displaced plants.
  • each fan (11) is mounted in a gain (13) or a similar duct. It is fixed on a practically vertical shaft (14).
  • This shaft (14) is guided so as to be able to rotate on itself in a bearing (15) fixed on the crosspiece (9) of the frame (1). It carries near its upper end a pulley (16) for driving the fan in rotation (11).
  • This drive is provided from a distribution housing (17) provided on the frame (1) (see Figures 1 and 2).
  • This housing (17) comprises an input shaft (18) which is directed towards the front and an output shaft (19) which is directed upwards and carries a pulley (20).
  • the input shaft (18) is intended to be connected to the PTO shaft of the tractor via a cardan shaft.
  • the pulley (20) of the output shaft (19) is connected to the pulley (14) of each fan (11) by means of transmission belts (21).
  • Each fan (11) has blades (22) for blowing air in the direction of the arrows (B). These blades (22) are orientable in order to be able to adjust the flow rate of the blown air. For the same purpose, the fan speed can be increased or decreased.
  • each fan (11) is circular. Its diameter roughly corresponds to that of the corresponding fan (11). It may therefore vary depending on that of said fan.
  • This sheath (13) is directed substantially perpendicularly to the surface of the ground. At its lower end, it has a sleeve (23) which is fixed to the sheath (13) by means of a clamp (24).
  • This sleeve (23) can be moved along the sheath (13) and be immobilized in different positions using said collar. This allows you to change its distance from the ground. In this way, the operator can regulate the air supply and adapt it to the nature and quantity of the plants to be moved.
  • This sleeve (23) can be made of a flexible material such as rubber. Therefore, it does not risk being damaged in the event of encountering an obstacle which may be on the surface of the ground.
  • Each of these sheaths (13) has several lateral openings (25) in its wall. These openings (25) are small. They are located one above the other and are oriented in the direction towards which the plants moved during work are directed.
  • the air inlet ducts (13) of the three fans (11) of the machine shown in Figure 1 are arranged along a line (L) oblique to the direction of travel (A).
  • This line (L) forms with said direction of advance an angle whose value is between 110 ° and 150 °.
  • the orientation deflector (12) extends around the lower parts of said gains (13). It consists in particular of an upper wall (26) and side walls (27 and 28).
  • the upper wall (26) is substantially horizontal and is located at a distance of approximately 50 to 60 centimeters from the ground during operation. It is crossed by the sheaths (13).
  • the side walls (27 and 28) extend from the upper wall (260 practically to the ground. They are advantageously made sées in a flexible material such as rubber to avoid damage in the event of encountering an obstacle.
  • the wall (28), which is located behind the sheaths (13), is practically parallel to the oblique line (L).
  • the wall (27) which is at the front of these sheaths (13) - seen in the direction of advance (A) - is located at a certain distance from said sheaths (13) and moves away from it as and as it moves toward the rear of the machine. Between the sheaths (13) and this front wall (27) of the deflector (12) is created a channel in which the plants move.
  • the rearmost part of the deflector (12) has an opening (29) allowing the plants to exit the aforementioned channel in the form of a swath.
  • This opening are provided guide rods (30) made of spring steel. They are applied to plants so that they prevent their dispersion.
  • the rods (30) which are located at the upper part of the opening (29) are connected to a support (31) which is articulated on the upper wall (26) of the deflector (12). This assembly allows a large clearance of these rods, for a good adaptation to the volume of plants moved.
  • the deflector (12) has an independent side part (32) which is articulated on the frame (1). It can thus be tilted upwards to reduce the width of the machine during transport and / or to enlarge the output of the plants in order to carry out tedding work.
  • shutter flaps consist of discs articulated on the sheaths (13) and having a diameter be substantially equal to that of said sheaths. They additionally include a cutout (34) for the passage of the shafts (14) of the fans (11). These discs can be brought above the ducts (13) in order to prevent the arrival of air during small work interruptions which do not require a complete stop of the fan drive (11). They can also be used to protect the fans when the machine is not in use.
  • the frame (1) also has on its side of the most forward fan an arm (35) carrying a wheel or a separating disc (36). This wheel is inclined relative to the direction of travel (A). At work, it rolls on the ground and separates the plants located in the path of the machine from those still spread out on the ground.
  • the machine according to FIG. 2 comprises a frame (37) of essentially rectangular shape. It has at the front a three-point coupling device (38) and at the rear of the swivel casters (39 and 40) which are adjustable in height.
  • the movement device (41) of the cut plants consists of four sheaths (13) each having a fan (11).
  • sheaths (13) are arranged in pairs on lines (M and N) forming a V, the point of which is directed towards the rear - seen in the direction of advance (A).
  • the ducts (13) and the fans (11) are similar to those described in connection with the machine according to FIG. 1 and will no longer be described in detail.
  • the four fans (11) are also rotated by means of belts (42) from a timing case (43) provided on the frame (37).
  • the lower parts of the air intake ducts (13) are surrounded by an orientation deflector (44) formed in particular by a substantially horizontal wall (45), a front wall (46) and a rear wall (47). .
  • the wall (45) is located at a distance of approximately 50 to 60 centimeters above the ground and is crossed by the sheaths (13).
  • the front wall (46) is substantially perpendicular to the direction of travel (A), while the rear wall (47) is substantially parallel to the lines (M and N) and also forms a V.
  • an opening (48) In the tip of this V is provided an opening (48) for the removal of displaced plants.
  • guide rods (49) for shaping the swath in formation.
  • each sheath (13) is equipped with a shutter (50) which is movable around its hinge axis (51).
  • At least one of the sides of the frame (37) is provided with an arm (52) which carries a wheel or a separating disc (53) to separate the plants located in the path of the machine from those still spread over floor.
  • the machine according to figure 1 is moved on the ground by means of a tractor.
  • the fans (11) of its displacement device (10) are rotated and blow air substantially vertically towards the ground.
  • These air jets are almost broken and returned upwards by the ground. They then lift all the plants spread on the ground and lead them towards the opening (29) located on the rearmost side of the machine.
  • the flow and power of the jets can be adjusted according to the nature and quantity of the plants.
  • the deflector (12) channels the air flow and guides the plants towards the opening (29). This flow is additionally reinforced and directed by the air passing through the lateral openings (25) of the sheaths (13). This air also prevents the plants from engaging between two neighboring sheaths (13).
  • the machine of Figure 2 is also moved by means of a tractor.
  • the air blown by the fans (11) of its displacement device (41) is then channeled towards the middle of the machine and it drives the plants towards the opening (48) of the wall (47) of the deflector (44). .
  • the machine forms a central swath.
  • the method of pneumatic displacement of plants which is described above can also be used on harvesting machines such as mowers, presses, harvesters or forage harvesters.
